I recently wrote about Privacy and Webmentions to make the case — mostly to myself — for adding Fediverse integration to Pure Comments . A few people pushed back in the comments, but my position could generally be summarised with "if it's a public post, it's fair game." Then this morning I read this post by Manu and it's completely changed my opinion. Having now read the Webmention spec it never presents Webmentions as being "comments". At all times they're referred to as "no...

Since learning about the effects of high CO2 concentration on attention and cognitive performance—especially at levels much higher than 2000ppm—I've started monitoring CO2 and other air quality indicators in my house, at my studio, and even on the road. I have a few other air quality monitors I'll be covering in the future, but today I wanted to focus on one I only heard about in the comments on a recent video tearing down a cheap no-name 'Air Quality Detector' from Amazon . Since l...

A forlorn businessman resting his head against a wall beside a window. Photo by Andrea Piacquadio, via Pexels. In the hours following the release of CVE-2026-89078 for the project Ruby , site reliability workers and systems administrators scrambled to desperately rebuild and patch all their systems to fix a double free in Ruby's Onigmo regular expression parser when parsing fails after an alternation, allowing memory corruption and potential remote code execution in applicat...

By Roberto Perez Alcolea , Java Platform Team Quasar connects a proposed API change with observed references in consumer repositories, giving the producer evidence for a release decision At Netflix, shared Java libraries support applications developed across a large, independently evolving repository ecosystem. A library change begins in one repository, but its impact can reach many others. Producers can see the API diff in front of them. What they often cannot see is who still depends on the...

FedEx closed fiscal 2026 with about 300,000 permanent full-time and 230,000 permanent part-time employees, according to its 10-K for the year ended May 31, 2026. Two business exits followed: FedEx Freight on June 1 and FedEx Supply Chain on October 1.

Originally published on Rails At Scale . The title was bait to get you to open this article. But fear not! We will be generating code at run-time today. (See the PR for a sneak peek.) Sam popped into the JIT channel asking how we might optimize Rails enums in Roundhouse, motivated by the following code snippet: class Order ruby -I~/git/ips/lib test.rb -- create_table(:orders) -> 0.0073s shippable?: 1.721M i/s (± 2.3%, GC 4.4%) aaron@Aarons-MBP ~/g/rails (main...

Decision models have exploded onto the scene recently, starting with TypeSafe’s Jev, followed by Perplexity’s Decider, Liquid’s d1, Cloudflare’s Clef, and OpenAI’s Decisions API 1 . These models promise fast, inexpensive classification. Decision models are an appealing low-cost alternative to LLM judges 2 for automated evals. But whether they’re the right choice depends on the cost, performance, and latency requirements of your use case. We’ve also noticed people using the def...

A recent Anthropic blog post contained a short paragraph, not at all the point of the post, which has been buzzing around my brain since I read it: A new level of operational excellence is possible. Our team uses Claude Tag heavily, which has helped us monitor each component of the system. For example, we created Slack channels where we tasked Claude with being obsessively focused on the health of a single component. We call these Claudes “superfans.” We have a scion-daemon superfan, a...

I was on a mini adventure in Hornsby Heights in northern Sydney during my lunch break earlier this week, because I… Hey, wait a minute. What does that say? Huh, ethernet! Is that what it is? Wow, it really could be! Oh, okay. Maybe they’re more into IB. By Ruben Schade in Sydney, 2026-10-24. I was on a mini adventure in Hornsby Heights in northern Sydney during my lunch break earlier this week, because I… Hey, wait a minute. What does that say? Huh, etherne...

After hiking up to the end of the ridge, it was now time to scout the initial part. The starting point is some 25km east of where I parked the car last time around, at the parking spot of the Italian ossuary in the lovely town of Kobarid. The plan is to walk my way up till the beginning of the ridge, reaching Starijski Vrh at the foothills of Mount Stol, the highest point of the entire ridge, at 1673 meters. The reason why I’m doing this hike is that I read conflicting information abou...

For the last month I have had a bag of coffee in the cupboard with enough beans to make one or two cups. I usually drink tea on weekdays, and prefer to have coffee while I am out and about, but because there is a storm forecast, and we had a storm yesterday evening too, I thought I would stay cosy this morning and take a slower day. This coffee will come in handy. When I went to make my coffee this morning, I had to prepare all my equipment that had been stowed away in my cupboards behind and...

Following our blog on Autonomy Factories , this is the second in our series exploring autonomy. An unmanned aircraft is tracking a vehicle during an intelligence, surveillance, and reconnaissance mission. The vehicle disappears beneath the tree line. As the aircraft searches the surrounding terrain, its communications link is disrupted and the operator loses contact. The operator can no longer intervene, but the mission must continue. The aircraft’s mission autonomy software, or autonomou...

Gergely Orosz is frustrated at those that entered his explicitly “No AI” essay competition and used AI. He goes on to say: When I start to suspect some part is AI about someone I don’t know: how can I tell how much of it is? And how much time and effort do I want to invest to figure out? I fear most people do not realize this last part: that when it takes time and effort from others to figure out what % is AI, and what % is YOU, then I will simply assume it’s probably 100% A...

In fall of 1985 when I started graduate school, my advisor Michael Sipser asked me to read an early handwritten manuscript by Johan Håstad of his switching lemma . I spent many hours decoding the notation and working through the messy conditional probabilities until I felt I had checked every step of the proof. When I started presenting this to Sipser, he stopped me and said he didn't want the details but instead the intuition of the proof. I had nothing. I'm reminded of this story as I hea...

We are entering an epoch where it may become easy for small pieces of self-replicating code to permanently infest Internet-connected devices in a way that is hard to undo. Such a world would be annoying to live in and we should take steps to forestall it. Anyone who used email in the 1990s remembers a similar, primitive era, when worms and viruses briefly ruled the net. But the connected world of that time was too simple to sustain an ecosystem of rogue escapees. Even today, much of the intern...

In medieval Italy, it was accepted wisdom that anyone walking near a swamp risked falling ill from “bad air” — mala aria. Victims were struck with fever, headache, nausea, and chills, and occasionally the illness escalated to vomiting, jaundice, and death. Today, we still call this affliction malaria. For much of human history, it has ravaged populations in humid tropical and subtropical regions… Source In medieval Italy, it was accepted wisdom that anyone walking near a swamp risked ...

Hello, Welcome to another Friday. This week marks exactly 2 years since the Space Age release . 2.1 Stable After a long summer in experimental, 2.1 is now marked as stable. Thank you to everyone who played the experimental, reported bugs, and gave us feedback. A lot of the changes and tweaks since the first 2.1 release came directly from your reports. We took this opportunity to update our classic Factorio trailer one last time. As ...

I’ve been working as a fractional CMO and enterprise SEO consultant for over 2 years now. So yes, I’m going to spend the next 1900+ words convincing you how colossally stupid it would be for you to hire me. Or any other fractional CMO. What You Actually Get When Hiring a Fractional CMO You may think you’re getting a third of someone’s time at a third of the price. You are not. It’s more like 15% of the time at 50% of the price. First, the full-time CMO baseline...

Many people are saying that AI will make software faster by rewriting it in faster languages, but this isn’t generally true. Most programs cannot be meaningfully sped up by rewriting them in C or Rust. How can this be true? Some languages are orders-of-magnitude faster than others: for instance, C can be fifty times faster than Python. Won’t rewriting my Python program in C thus make it fifty times faster? No, it won’t. Software performance is usually dominated by I/O, not the speed ...

I Just Can’t Wait to Be King in 16:9, running as native code. TLKRecomp is The Lion King for the Super Nintendo, rebuilt as a native PC program. It runs on Linux, Windows and Mac, plays from the Westwood logo to the final fight with Scar, and can widen the picture to 16:9. It took ten days, and AI agents wrote the code. They worked in a loop: try something, compare it frame by frame with the original game, find the first thing that differs, fix it, and go again. This post explains ...

My latest vibe coded game experiment is a Command & Conquer style RTS (Real Time Strategy) game called Battle Drones ( play it here ). Unlike my previous experiments , this one is actually fun to play . I'm somewhat embarrassed to admit that I got there by telling Claude to "Make it a LOT more fun". It also supports multiplayer between nearby devices using audio to synchronize game state! Here's what I've built so far, and some of the things I learned along the way. Battle Drones ...

I’m assuming you all gave a sigh of relief when you saw digital text rather than scans of my handwriting. This post is largely a set of updates and corrections to my previous post; given the lack of revisions I have some corrections to make. Beyond that, the lack of reflection on my thoughts during the editing process had me coming to realizations after hitting post, alongside a few misc updates. I’m assuming you all gave a sigh of relief when you saw digital text rather than scans of my ha...
